SOLUTION:
1) The y-intercept is the value of the function, for x = 0.
2) So, to find the y-intercept when you have the function, you need to solve the equation for y when x = 0.
For example if the function is y = f(x) = x^2 + 5, the y-intercept is y = f(0) = 0^2 + 5 = 5. 3) Graphically, the y-intercept is the point
where the graph of f(x) crosses the y-axis.
So, if you have the graph, you just read the value of the function on the y-axis.
Taking all that information, you do not report the y-intercept as a pair of coordinates. The y-intercept is reported just as a value for y.
For example, assuming that the point (0, - 4) you do not say that the y-intecept is (0,-4), you say that the y-intecept is -4, because that is the value of the function when x = 0.

Step-by-step explanation:
GIVEN: A bicycle training wheel has a radius of . The bicycle wheel has a radius of
.
TO FIND: Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel.
SOLUTION:
radius of bicycle wheel
area of bicycle wheel
putting value,
area of bicycle wheel
radius of bicycle training wheel
area of bicycle training wheel
putting value,
area of bicycle wheel
difference in area of bicycle wheel and bicycle training wheel
hence the training wheel is smaller than regular wheel
